But why does she have to take chemotherapy as her medical treatment what if she wants to do holistic healing or alternaitve medicine?
If she wishes to try those methods, she may as well put the noose around her neck right now. I understand she is scared, but she needs to suck it up and accept that unless she chemo, she will die.
What makes you think she hasn't "sucked it up and accepted it"? Just because she didn't then make the choice YOU think she should have? How is it your place to tell her what she needs to accept and not accept, anyway? You certainly wouldn't approve of the state stepping into YOUR personal choices on how to live your life, despite what a waste that life turns out to be. So why do you get to tell her she has to do anything?
